Healing stones
Rather than use water or steam to heat and wash the body, people simply wear a gown or something comfortable, and then lay on heated stone tablets made of granite or silica, which are warmed to around 45 C.
"The body will gradually warm up and circulation will also be improved. More sweat will come out quickly. The sweat is smooth and fresh, not smelly and sticky like that released after sports activities. Such sweat comes from the deep inside of the body," says a worker surnamed Tan at Shanghai Yishengtang, a hot-stone bath provider.
"Many clients come here to seek this detoxification effect, especially in summer," he says.
Ganbanyoku service providers claim such baths bring a number of health benefits, such as anti-aging, improved blood circulation, body detoxification and stress relief. The slimming effect of dieting can even be boosted, they say.
Compared with hot-stone therapy on the body, such a hot stone "bath" is relatively rare in China, though it can be found in some big cities like Shanghai and Beijing.
For such a spa treatment, it's necessary to rest and relax beforehand. Also, do not eat too much before the massage, Tan notes.
"Hot-stone therapy is not suitable for everyone, and it's is not recommended for people with infectious skin disease, open wounds or heart diseases. Pregnant women are also not advised to have it," he says.
"I used to feel chilly and have cold feet in winter. It's really comfortable when feeling the warmth of the hot stones, and the whole body is getting relaxed," says Sophie Chen who works with a multinational company in Shanghai.
"Sweating is a good thing. It will help release negative impurities. When I finish the whole course of a stone bath, I feel my body is cleaned up," she says.
